That might be nice. It would also answer the people who want to do the gzip themselves (to optimize p7zip style) but use the high level part of zipfile.

Depends. If by "it" you mean "Python" in the abstract... There's no answer to that.

If you mean CPython 2.7.0-2.7.4 or 3.3.0-3.3.1, then you can verify it pretty easily (and I suspect the OP already did).

Which means if you do this from outside, you'll want a comment explaining why it works, and which versions of Python you've verified it against.
